Let's take a look at a program which will return different greeting messages according to the time of the day.
We will write a Scala program with the main class name of Greet
having a function named greet
which would return different greeting messages as described below, according to the time input to the function.
Input time - 4 to till before 12 : Message Output - "Good Morning"
Input time - 12 to till before 16 : Message Output - "Good Afternoon"
Input time - 16 to till before 21 : Message Output - "Good Evening"
Input time - 21 to till before 4 : Message Output - "Good Night"
Example Usage:
If we execute Greet.greet(5)
, then it should return "Good Morning"
If we execute Greet.greet(12)
, then it should return "Good Afternoon"
and so on...
Write the code in Jupyter and press Shift + Enter. Your code should look like the following:
object Greet{ def greet(hour:Int):String = { if (hour >= 4 && hour < 12){ return "Good Morning" } <<< YOUR CODE>>>> } }
Test the function with various inputs to make sure that it is returning the outputs as per requirements.
